Add package command support: This PR adds package command to CLI. package provides some useful subcommands to use such as packages CRUD and display package detail information. Also it is able to reuse existing package at function creation.
* Check function existence before creating package
* Check package existence
* Add support for downloading archive from given url
The functionality was supported before e238776bf7. Add this functionality back for more flexible usage.
* Add output flag to save archive content in specific file
* Add logs when package create/update
* Fix fnCreate requires environment argument when a pkg is specified
* Fix fnUpdate failed to update function pkg info when a package is specified
* Add package command test
* Fix wrong python test image in test script
* Remove package description fields
* Fix package command not update package but creating a new one
* Set package as pending status only when there is no deploy archive
* Rename function from fetchArchiveFromArbitraryURL to downloadToTempFile
* Use io.Copy to prevent loading all body into memory
* Revise some messages
* Allow user to update package build command
* Allow user to update package content when using function update
* Retrieve pkgName from function packageref if it’s not specified
* Fix function failed to update due to resource conflict
* Fix test case failure due to single quote
* kick ci
* Fix failed to update function packageRef
* kick ci
* kick ci
Remove the `logger` container from the logging daemonset.
Remove the outgoing call from the poolmgr to the logger. Use Fluentd's Kubernetes filter to add function name and UID to influx metadata.
This means fluentd now figures out when to start collecting function logs on its own, without being informed by poolmgr. This is great for other execution strategies, and for autoscaling, where fission isn't in direct control of function pod creation.
Also adds an integration test to make sure logging keeps working.
This contains a few different builder manager fixes:
* Update the zip file structure to avoid an extra subdirectory
* Annotate packages with what functions are using them
* Only trigger builds when there is no deployment archive
* Python environment loadpath bugfixes
* Other bugfixes
Switch Fission's storage over to the new CustomResourceDefinitions, from the deprecated ThirdPartyResources. This allows us to be compatible with Kubernets 1.8 and onwards.
This also adds a CLI tool for dumping state from an old fission version and restoring state into new CRDs.
The storage service is unaffected by this change.
This change orchestrates function builds.
Environments (in v2) define a builder image, just like they do a runtime image. The builder image contains a build script that's invoked with source and deployment paths (as env vars).
The buildermgr watches for environments with build images defined, and creates build deployments and services.
Functions can define source and deployment. Buildermgr watches for functions with source code (and build status == pending) and invokes the environment's builder when appropriate. It captures logs from the build and sets the build status (success/failure) and build lots into the PackageStatus.
Allows dumping v0.1 state to a json file and restoring it into a new v0.2.1 fission installation.
Usage guide is at: /Documentation/docs-site/content/upgrade-from-v0.1.md
Introduce _Archives_ as a type to reference arbitrary blobs.
_Packages_ are a pair of Source and Deployment archives. Packages have an environment reference.
Functions reference a package. Multiple functions can reference the same package.
This change contains CLI support for uploading large functions to the storage service.
It also adds a reverse proxy into the storage service to the fission API.
The helm chart is not yet updated to actually run the storage service -- that will come in the next change.
Split out the Package type into a first class Kubernetes resource. Before this change, packages were implicitly tied to functions.
This wasn't ideal because:
* Functions will need to share packages
* A package storage system may be more generally useful than just
functions (for example, for storing static assets)
This change does the following:
* Updates the fission and tpr types to add a new Package and PackageSpec. It also creates a PackageRef type, and a FunctionPackageRef type. The PackageRef simply references a package, but the FunctionPackageRef includes the name of a function within the package. This allows us to share packages between different functions.
* Updates fetcher and other components for first-class packages
* Allows customization of fetcher image pull policy in the helm charts
This changes the core fission function, environment and trigger types. It also changes Fission's storage to use ThirdPartyResources.
- Functions are now specified by packages. Functions can also have both source and deployment packages. A package can be specified by a literal, or by a URL.
- Environments have a build and runtime component.
- Triggers reference functions by a FunctionReference. This is a layer of indirection between triggers and functions, and will allow things like incremental function upgrades in future releases.
See Documentation/wip/env-v2.md for design discussion about points 1 and 2.
Changes:
* V2 Types
All types now have a spec, following the pattern of K8s objects.
Functions now have source and deployment packages. A Package can be
specified by literal, or by URL.
Environments now have a builder and runtime component.
All triggers use a new FunctionReference to specify the function. This
for now only uses a function name, but in the future can be extended
to be more flexible.
A new FunctionLoadRequest type is added for specialization requests to
the environment runtime.
* TPR types, TPR init code, and a "fission client"
Implements TPR types using the spec types in fission/types.go.
Adds code for adding creating TPR types, and convenient types for crud
operations on each of our resource types.
Adds code for connecting to K8s API and configuring a REST client with
fission types set up.
* Change old stateful controller into a thin apiserver
This apiserver is now simply a stateless api layer on top of the TPR
types. At the moment it doesn't do anything that couldn't be done by
simply talking to the TPR types. In the future we can have better
validation and potentially some higher level APIs (like versioning for
example) in here.
* Split controller client into files and update for v2 types.
* Update CLI for v2 types.
As far as possible we keep the CLI flags the same. We'll have to add
flags for source/deploy packages and builder/runtime
environments. That will come in the next change.
* Update poolmgr and fetcher for v2 types.
Also adds a poolmgr_test.
* Update router for new types.
Also adds a function reference resolver, which separates out the job
of resolving a FunctionReference to a function.
* Update kubewatcher and timer for v2 types.
* Update Message Queue trigger type for v2 types.
* Minor odds and ends.
* Fission bundle CLI updates
Remove controllerUrl flag, since we don't need it any more.
* Remove etcd deployment (replaced by storing state in TPR)
Also update the poolmgr commandline, and use an env var for the
fetcher image URL.
* Explicit ChecksumType and consts
* Clarify separation of environment interface types
Adds support for message queue triggers based on the NATS-Streaming message queue.
This lets the user map a queue topic to a function, and optionally send the function's response into another queue topic.
The message queue trigger manager is designed to be message queue independent, so we should be able add support for more queues by adding implementations for the relatively simple mqtrigger.MessageQueue interface.
* Fix controller timer handler not return when error occurred
* Fix controller not close http response correctly
This PR aims to fix controller not close response correctly. Also, I’ve check all over the project there is no more resource leak issues exist after this patch.
* Fix controller not return immediately when error occurred
* Sort import
Establish a proxy server from the controller to the log database.
Redirect query commands send from client to database then proxy back the db response.
Use parameter binding instead of fmt.Sprintf to prevent SQL injection.
This change adds a timer trigger API, client, and implementation. Users can trigger a function with a cron-compatible string.
This change also moves the publisher interface and webhook-based publisher implementation out of kubewatcher and into a separate `publisher` package.
Add function log aggregation and persistence using Fluentd and InfluxDB.
Fluentd and a helper sidecar run as a daemonset. The poolmgr sets up logging for each function pod, using the helper sidecar. Fluentd forwards logs to InfluxDB, which is run as a deployment and service. The client CLI directly queries InfluxDB for logs.
Fluentd supports many outputs besides InfluxDB, so we aren't very tied to InfluxDB.
The setup is somewhat manual, which we should be able to improve by integrating this into the helm chart.

Minimal golang runtime.
Functions are built as Go plugins, and the plugin is uploaded to fission.
See `environments/go/README.md` for instructions and `examples/go` for a usage example.
For now, we're re-using the 'code' field of the function to store the binary plugin. With v2 environments, this will be stored separately as a binary package.
This allows users to add --method and --url params to their "fission
fn create" command line. It sets up the route to call the latest
version of the function; user can edit the route with the "fission
route update" command, if they want to.
